The Perfect Progressive theory in Malay Grammar refers to the combination of the perfect tense and progressive tense to indicate an ongoing action that started in the past and continues in the present. In Malay, this is expressed using the word “telah” (have/has) or “sudah” (already) together with the verb followed by the word “sedang” (in the process of) and the verb root with the suffix “-kan”.

For example, “Saya telah sedang memasak sejak pagi tadi” translates to “I have been cooking since this morning”. Here, “telah” indicates the action is completed, “sedang” indicates it is ongoing, and “memasak” means cooking. The use of past tense or adverbs like “sejak” (since) or “tadi” (earlier) shows that the action started in the past.

This grammar concept is useful in everyday conversation, especially when talking about ongoing activities or explaining situations that started in the past and are still continuing. By understanding the Perfect Progressive theory, learners can express actions or events in a more accurate and detailed manner.
